“…The free gingival graft will help in the prevention of further recession [ 20 ]. Lesser invasive procedures like the use of collagen matrix-like Geistlich Mucograft® (Geistlich Pharma AG, Wolhusen, Switzerland) and Mucoderm® (botiss medical AG, Berlin, Germany) can be used as an alternative to autogenous grafts like free gingival grafts for the treatment of such similar scenarios [ 13 ].…”

This case report describes Clark’s technique of vestibuloplasty to treat shallow vestibule and, in addition, the use of free gingival autograft to augment attached gingiva to treat Miller’s recession. Vestibuloplasty is performed to deepen a shallow vestibule. Different vestibuloplasty techniques are used to deepen the shallow vestibule by modifying the soft tissue attachment. A 29-year-old male presented to the Department of Periodontics and Oral Implantology, Regional Dental College, Guwahati, India with the chief complaint of bleeding from the lower anterior along with the gingival recession. Maintenance of regular oral hygiene was an added hindrance. The combined technique of vestibuloplasty and use of free gingival graft was performed to achieve dual benefits of increasing the vestibular depth and attainment of a thick gingival phenotype.

“…Vellis et al found that CM (gain 4.4 mm) achieved comparable results to FGG (gain 4.6 mm), and the two approaches do not affect probing depth, marginal recession and bleeding on probing [40]. Huang et al showed that FGG (gain 4.1 mm) could result in greater increase of KMW than CM (gain 1.7 mm), though both could increase KMW, maintain peri-implant health, and attain comparable aesthetic outcomes [41]. Fu et al reported at 6 months, the KMW was signi cantly higher with FGG (3.74 mm at 6 months) than with CM (2.82 mm at 6 months) in the posterior mandible [42].…”

Objectives: Evidence on the decision-making of keratinized mucosa (KM) augmentation procedures around dental implants is lacking. The aim of this study was to evaluate the effectiveness of KM augmentation with different techniques around dental implants based on risk assessment. Materials and methods: Thirty-nine patients who underwent KM augmentation at implant sites in the posterior mandible were included. Three different techniques were used based on risk assessment: apically positioned flap (APF alone), apically positioned flap plus free gingival graft (APF plus FGG), and apically positioned flap plus collagen matrix (APF plus CM). Keratinized mucosa width (KMW), implant/prosthesis survival rates, and bone/soft tissue parameters were analyzed. The correlation between local anatomy characteristics and different techniques was tested separately. The association between KM augmentation outcomes and related factors was analyzed using linear model. Results: In overall, 74 sites received KM augmentation in the lower jaw, with an effective rate of 94.6% in 1-year follow-up and 93.2% in 5-year follow-up.KMW for APF plus FGG group (3.85±1.22 mm) appeared to be higher than those for APF alone group (3.05±0.90 mm) and APF plus CM group (3.21±1.17 mm) after 5 years. There was no significant difference on the effective/ineffective outcomes in 1-year and 5-year follow-up among the three groups. Conclusions: Comparable effective outcomes would be achieved with three different KM augmentation techniques following the decision-making criterion based on risk assessment. Study registration: Chinese Clinical Trial Registry (ChiCTR2200062113) Clinical Relevance Scientific rationale for study: The clinical effectiveness of KM augmentation procedures around implants has been documented. However, limited studies reported detailed anatomical characteristics and evidence on the decision-making of KM augmentation procedures around dental implants is lacking. Principal findings: APF plus FGG could achieve more KW than APF alone and APF plus CM, though there was no significant difference on the effective/ineffective outcomes in 5-year follow-up. Practical implications:Risk assessment according to anatomical characteristics is necessary before the KM augmentation surgery. Comparable effective outcomes can be achieved with different KM augmentation techniques following the decision-making criterion based on risk assessment.

Background: Peri-implant mucosa color (PMC) seems to be one of the main parameters affecting the esthetic outcome of implant therapy. However, more emphasis should be given to its assessment and reporting.Purpose: To describe the available evidence on methods to assess and report the color of the peri-implant mucosa (PMC) and the respective clinical relevance.Material and Methods: A comprehensive electronic and manual search was performed to identify clinical studies reporting on PMC.Results: A total of 121 studies were included. PMC was evaluated at the time of the follow-up visit (chairside) in 45.5% studies. PMC assessment was performed qualitatively, by comparing PMC with adjacent and/or contralateral gingiva (78.6%) or quantitatively, using spectrophotometry (20.7%) or a software on clinical photographs (0.8%). The most performed method to assess PMC was through esthetic indices (76.9%), either at the time of the follow-up visit (chairside) or at later time point using photographs. Quantitative reporting of PMC included averages of points from esthetic indices or color differences to natural gingiva expressed with the CIELAB color system. PMC assessment allowed describing color discrepancies compared to natural gingiva, evaluating color changes over time, and comparing the outcomes of different treatment modalities. PMC assessment through spectrophotometry was additionally utilized to assess the role of mucosal thickness (MT) on PMC.Conclusions: Various methods for PMC assessment and reporting were described, including visual assessment, mainly through esthetic indices, and spectrophotometry.PMC evaluation has allowed to demonstrate the factors affecting the color of the peri-implant soft tissue, such as the type of abutment/restoration, MT, and soft tissue augmentation.
